Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment who obtains under creative work prerequisite, all belong to the scope of the utility model protection.
Direct wind-driven generator group sealing configuration the utility model embodiment being provided below in conjunction with accompanying drawing is described in detail.
The schematic diagram of the direct wind-driven generator group sealing configuration that Fig. 2 provides for the utility model embodiment.As shown in Figure 2, the direct wind-driven generator group sealing configuration that the utility model embodiment provides, comprise circular groove type assembly 21, the external stability of the first side 211 of circular groove type assembly 21 is on generator amature assembly 22, outside in the second relative side 212 of the first side 211 is provided with air guide sleeve 26, and there is predetermined gap between circular groove type assembly 21 and air guide sleeve 26, on air guide sleeve 26, be fixedly connected with hairbrush assembly, and hairbrush 23 in hairbrush assembly contacts to form with the first side 211 seal space that blocks predetermined gap.
The utility model embodiment provides a kind of direct wind-driven generator group sealing configuration, compare from direct wind-driven generator group sealing configuration of the prior art and different be, the sealing configuration that the utility model embodiment provides is also fixedly connected with hairbrush assembly on air guide sleeve, and hairbrush in hairbrush assembly also with the first side contacts of circular groove type assembly to form the seal space that can block circular groove type assembly and air guide sleeve joint predetermined gap.This seal space can stop that extraneous sleet and dust enter into wind power generating set effectively, even if make wind power generating set long term exposure in the time of the external world, also the continuous accumulation that can avoid sleet and dust to enter into wind power generating set and produce therein, thereby the normal operation of guarantee wind power generating set.
In order to form good sealing to the predetermined gap having between circular groove type assembly 21 and air guide sleeve 26, on air guide sleeve 26, be connected with hairbrush assembly, and hairbrush 23 in hairbrush assembly contacts with the first side 211 of circular groove type assembly 21.In the time that hairbrush 23 contacts with the first side 211 of circular groove type assembly 21, can protect preferably wind-driven generator not to be subject to the invasion and attack of extraneous sleet and dust, for better ventilation and heat of wind-driven generator inside, the hairbrush 23 in hairbrush assembly is Elastic Contact with the contact form of the first side 211 of circular groove type assembly 21 simultaneously; Or adopt the way of contact that hairbrush 23 and the first side 211 of circular groove type assembly 21 are Interference contact.The seal space forming like this can either be avoided extraneous sleet and the invasion and attack of dust to wind-driven generator, can ensure again the efficiently radiates heat of wind-driven generator inside.
In order to meet the demand of the sealing configuration in the utility model embodiment, hairbrush 23 should have the feature that mechanical strength is high, softness is high, can carry out work under hot and humid environment.In the present embodiment, hairbrush 23 is preferably nylon wire hairbrush.
In the sealing configuration providing in the utility model embodiment, predetermined gap is 30-40mm.It is in order can better to dispel the heat to wind power generating set that predetermined gap is set to 30-40mm, thereby ensures the normal operation of wind power generating set.In addition, the radial dimension of the first side 211 of circular groove type assembly 21 is greater than the radial dimension of the second side 212.In the time that the radial dimension of the first side 211 is greater than the second side 212, the hairbrush assembly being located on the air guide sleeve 26 in the second side 212 just can form and better contact with the first side 211 of circular groove type assembly 21, thereby can avoid preferably hairbrush 23 and the generator amature 22 of circular groove type assembly 21 outsides friction occurs and it is produced and is disturbed.
In addition, hairbrush assembly comprises hairbrush carrier 25, and carries hairbrush 23 on hairbrush carrier 25.Wherein, hairbrush carrier 25 can be the annular arranging around air guide sleeve.By hairbrush 23 by hairbrush carrier 25 around being fixed on air guide sleeve 26, can play fixation to hairbrush 23 preferably, and can form and better contact with the first side 211 of circular groove type assembly 21.Wherein, hairbrush carrier 25 is selected from the one in glass fibre reinforced plastics hairbrush carrier, aluminium section bar hairbrush carrier or stainless steel hairbrush carrier.The hairbrush carrier 25 being made by above-mentioned material has good hardness, can steadily hairbrush 23 be fixed on air guide sleeve 26.Optionally, hairbrush carrier 25 can be fixed on air guide sleeve 26 by connection part 24.Wherein, connection part can be rivet or bolt.
Obviously, above-described embodiment is only for example is clearly described, and the not restriction to mode of execution.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here without also giving exhaustive to all mode of executions.And the protection domain that the apparent variation of being extended out thus or variation are still created in the utility model.
